I have a LaTeX document. I want to change the font size of all the text, to make it smaller.

Normally I would just change the documentclass part. However I am generating LaTeX files from another programme, and it is setting the documentclass, I can't change that. However I can put things in the preamble.

Is there anyway to change the font size in the preamble, without touching the documentclass declaration.
